Excellent Python skills with a good understanding of relevant libraries.
Significant system design and architecture knowledge for highly distributed systems.
Ability to design, build and optimise high-performing Python systems from scratch.
Previous experience building/upgrading SQL databases would be highly desirable.
Good knowledge of source versioning systems

We encourage you to apply even if you think you may not currently fit all these requirements – so long as you have proven academics and are willing to work hard and learn, we want to hear from you.
